Who you going to call? Not your friends or family, because your phone is going to be tied up zapping ghosts in Beeline Interactive’s Ghostbusters game. You can download it right now on iPhone and iPad for free.

I have a little over an hour invested into this game, and I’m having a grand ol’ time with it. The screenshot above illustrates how most of the game works. All three of the characters can be moved individually by tapping them and drawing a line to the desired location. Attacking is handled the same way. Draw a line to an enemy and your character will blast away. Michelle Ying (the blue-haired girl) is using a traditional proton pack, which gives her a bit more range. Michael Prince is wielding a level 2 Slime Blower, a potent close-range damage-dealer. Tara Fitzpatrick’s proton pack works in similarly to Michelle’s, but it’s equipped with a M.E.D. upgrade used for healing. Draw a line to an injured party member and she’ll instantly switch from attacking to healing. This is the line-up I’m rocking right now. A fourth teammate – or replacement teammates – can be purchased back at the firehouse headquarters.
